Title: Terminal for flexible printed board
Inventor: ARIGA KATSUHIKO
IPC: H01R4/18
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To provide mechanical and electrical connection with successive stability by relaxing stress concentration on a flexible printed board (FPC). SOLUTION: An FPC 2 is placed on the installation face 10a of a terminal 1 and thrusted by the outer periphery of a barrel 11 in a cylindrical shape to be put in face contact with the barrel 11 while being prevented from damage for good electrical and mechanical connection to the barrel 11. Even if the thickness of the FPC 2 is reduced by stress concentration with secular change, the thrust by the barrel is effectively applied to the FPC 2. A serration 12 is provided corresponding to the barrel 11 in the (y) direction of the installation face 10a and, when tensile stress is applied to the FPC 2 in the (x) direction, the barrel 11 is locked to the serration 12 to prevent the looseness of the FPC 2.  A circuit 21 for the FPC 2 is elastically energized by the protrusion 16 of a contact spring 13 in a beam structure with one end fixed and the other end supported to stably provide electrical contact between a contact conductor 21 and the protrusion 16.

Title: Aligner
Inventor: KAMIYA SABURO
IPC: H01L21/027
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To minimize the effect of heat source, which is part of an aligner main body, in a chamber and also to suppress the vibration of the aligner main body caused by the noise of air-conditioning part. SOLUTION: A chamber 12 is divided into a main partition 44 and a sub partition 46 by a bulkhead 42, and a part of lighting system 16 comprising a mercury lamp 16a which is a heat source is housed in the sub partition 46, and in the main partition 44, other main part of an aligner main body 14 is housed. Since the bulkhead 42 is made of such material as high heat insulating characteristics with high sound transmissivity, no heat generated at the mercury lamp 16a in the sub partition 46 affects the main partition 44 side, further, even when a pressure fluctuation takes place in the chamber 12 due to the noise generated at a blower 58, a partial vibration does not take place at the aligner main body 14 as fluctuation is even in the main partition 44 and the sub partition 46.

Title: Method for controlling network circuit
Inventor: YOTSUMOTO HIROSHI
Filed: 1985-05-07
Abstract: PURPOSE:To reduce the load of a host computer by using both a contention system and a poling system and controlling the switching of both the systems. CONSTITUTION:When receiving a communication request of which requesting terminal is unkown in the contention mode, the host computer inhibits respective terminals to generate successive communication requests. When the contention mode is turned to the poling mode, the host computer inquires respective terminals to check the terminal generating said request, and then executes communication with the terminal concerned. After poling the whole terminals, the host computer releases the whole terminals from the inhibition of the communication request generation and returns to the contention mode again. Consequently, it is unnecessary for each terminal to execute retransfer processing at the time of collision, reducing the load of the host computer.

Title: Fault detecting device for motor current control system
Inventor: YAMAMURA YOSHINORI
IPC: H02P7/291
Filed: 1990-04-11
Abstract: PURPOSE:To detect a failure with high accuracy by providing a motor current estimating means and comparing an actual motor current with a motor current estimating signal. CONSTITUTION:A current commanding value Imc is supplied to a current control circuit 10 and a motor current estimating circuit 15. When the current commanding value Imc is changed stepwisely, an actual motor current Im, controlled by the current control circuit 10, rises up in accordance with a given time constant and, then, is settled to a given value. On the other hand, the motor current estimating circuit 15 rises up with a time constant same as said time constant and outputs then an output Imf settled to a given value. A subtracting circuit 11 obtains a difference (e) between the actual motor current Im and the motor current estimating value Imf while a comparing circuit 12 compares the difference (e) with a reference value (eR). When the difference (e) has exceeded the reference value (eR), the output S of a comparing circuit 12 becomes 'L' level. Accordingly, a transistor 9 is turned OFF and a relay 7 is turned OFF whereby a motor 1 is stopped.

Title: Data transferring system
Inventor: AKAO TAKASHI
IPC: H04L13/08
Filed: 1983-06-01
Abstract: PURPOSE:To transfer a data at a high speed and to increase the number of circuits which can be contained, by constituting so that a processing device receives in parallel only effective data from a data accumulating circuit of an IF circuit basing on a reception request signal and an output of a byte number counting circuit of the IF circuit. CONSTITUTION:In case a data transferred in series from a communicating device 1 is less than (n) bytes, for instance, in case a data Dd of (m) (n>m) bytes is transferred, when a data accumulatin circuit 2-1 of an IF circuit 2 accumulates a data of (m) bytes, a byte number counting circuit 2-2 decides it as end of accumulation by receiving the first one byte signal of an error detecting redundant bit FCS, outputs a byte number BN=(m) of an effective data inputted to the circuit 2-1, and simultaneously, gives an accumulation end signal E to a reception request signal generating circuit 2-3. When E is received, the circuit 2-3 outputs a reception request signal R, and a processing circuit receives only a data of (m) bytes from the circuit 2-1. When a block is continued by (n) bytes or more, no reception request is outputted unless a data of (n) bytes is accumulated in the circuit 2-1, therefore, it will do that a reception processing speed of the processing device is low.

Title: Diffusion coating heat-transfer pipe for sulfuric acid resistant dew point corrosion
Inventor: OZAKI MASASHI
IPC: F16L58/08
Filed: 1995-03-30
Abstract: PURPOSE: To prevent sulfuric acid dew point corrosion from corroding a heat transfer pipe surface and thinning the pipe wall, by applying the electroplating of porous Ni, including Mo fine particles, having specific thickness on the surface of a carbon steel pipe, and then giving diffusion-coating to metal Cr containing Al2 O3 powder to form the coat of anticorrosive Ni-Cr-Mo alloy. CONSTITUTION: In the coat of Ni-Cr-Mo alloy obtained by applying the electroplating of porous Ni, containing the Mo fine particles of 1-3μm, to a mainly carbon steel surface, and then diffusion-cementation-treating metal Cr, containing Al2 O3 powder, at 900-1100 deg.C degree; anticorrosion to sulfuric acid is kept by Ni, Cr, and Mo. Also, anticorrosion to sulfuric acid is excellent because of realizing the densification of a coat by the effect of diffusion-cementation- treating. Consequently, when an alloy coat, by porous electroplating + diffusion cementation treating excellent in sulfuric acid corrosion resistance, is formed on a heat transfer pipe surface; the alloy coat protect a heat-transfer pipe to improve the sulfuric acid corrosion resistance of the heat transfer pipe, thereby obtaining an anticorrosion heat-transfer pipe.

The MDS signal is counted during one revolution of an antenna by an MDS number-of- input counter 2 and latched by the antenna north signal sent from the radar apparatus. Next, the ratio of the number of the outputs of the dummy signal and the number of receiving inputs detected as receiving echos actually is calculated by an MDS detection ratio calculating circuit 3 to be outputted to a display device.

Title: Multi-stage hydraulic machine
Inventor: HISHIDA YASUO
IPC: F03B3/10
Filed: 1981-06-24
Abstract: PURPOSE:To simplify the structure around an upper cover of a multi-stage hydraulic machine, by increasing the difference between the water pressure at an upstream part of a highest-pressure stage runner and that in a side pressure chamber of a lowest-pressure stage runner, communicating these two sections with each other, and thereby producing a large axial thrust in an upward direction. CONSTITUTION:From a casing or an iron pipe, high-pressure water is introduced into a side pressure chamber of a lowest-pressure stage runner 1 so as to produce upward thrust at the runner 1 by this high-pressure water. Resultantly, downward thrust produced by a highest-pressure stage runner 3 is balanced with the upward thrust produced by the runner 1. Thrust adjustment is achieved by a control valve 19. With such an arrangement, it is enabled to omit a conduit for communicating a back-pressure chamber of the high-pressure runner 3 and  the side pressure chamber of the low-pressure runner 1 with each other.
